Abstract
A kind of comprehensive extracting and caving face returns device for coal, it is trapezium structure to return device for coal, the rear portion drag conveyor side of its upper surface is less than opposite side, return device for coal and rear portion drag conveyor side is connected to by connection ring, what connection ring included being welded as a whole returns device for coal handing-over ear and drag conveyor handing-over ear, rebound is fixed on connection ring top, rebound is less than go back to the upper surface of device for coal, returning inside device for coal has a supporting steel, returns device for coal handing-over ear and completes to connect by round pin axle with conveyer handing-over ear.After increasing back device for coal, improve coal recovery rate, during the Sub-Level Caving of underground, after drawing rear portion scraper-type to send machine, coal does not have to the height for first accumulating 300mm, but fall directly on back above device for coal, so as to be directly entered in the drag conveyor of rear portion, the ramp for returning device for coal is more conducive to the landing of coal.Coal 40 tons of yield of raising is often circulated by live actual calculate, under current economic condition, considerable benefit is added for enterprise.
Description
Technical field
The present invention relates to a kind of underground coal mine comprehensive extracting and caving face to return device for coal.
Background technology
With the continuous improvement of Mine Integrated mechanical coal mining technique, mine develops towards high-yield and high-efficiency direction, peace
Positive city's coking coal industry Co., Ltd working face uses hydraulic support model ZF2400-16/24 types, the front and rear laying two of support
Portion model SGZ-630/264 drag conveyor.Rear portion scraper-type send machine during coal is put with support assorted, due to scraper plate
Conveyer oneself height is 260mm or so, after drawing rear portion scraper-type to send machine, causes original place point space, is put during coal only
It could enter after coal piling height is higher than into rear portion drag conveyor inboard chute face in drag conveyor, pass through coal flow system
Coal Transport is gone out, causes every circulation 260mm Coal Loss, the rate of extraction declines.
The content of the invention
The technical problem to be solved in the present invention is：It is defeated without being stacked into rear portion scraper plate during production period Sub-Level Caving
The height of machine inboard chute is sent, puts during coal to coordinate by plate and rear tail boom and cradle top coal is directly placed into rear portion scraped
In plate conveyer chute, it is capable of the coal resources waste of reduction to greatest extent, effectively improves the rate of extraction.
To solve its technical problem, technical scheme is specially：
A kind of comprehensive extracting and caving face returns device for coal, and it is trapezium structure to return device for coal 2, and the rear portion scraper plate of its upper surface is defeated
Send the side of machine 1 to be less than opposite side, return device for coal 2 and the side of rear portion drag conveyor 1 is connected to by connection ring 5, connection ring 5 includes
What is be welded as a whole returns device for coal handing-over ear 4 and drag conveyor handing-over ear 3, and rebound 7, rebound 7 are fixed in the top of connection ring 5
Less than the upper surface for returning device for coal.
Returning inside device for coal has a supporting steel 6.
Return device for coal handing-over ear 4 and be provided with circular hole with drag conveyor handing-over ear 3, complete to connect by round pin axle.
The beneficial effects of the invention are as follows：After working face rear portion drag conveyor 1 adds back device for coal 2, improve first
Coal recovery rate, in the Sub-Level Caving work progress of underground, after drawing rear portion scraper-type to send machine 1, coal does not have to the height for first accumulating 300mm
Degree, but the top of device for coal 2 is fallen directly on go back to, so as to be directly entered in rear portion drag conveyor 1, return the ramp of device for coal more
Contribute to the landing of coal.Coal 40 tons of yield of raising is often circulated by live actual calculate, under current economic condition, is
Enterprise adds considerable benefit.
Brief description of the drawings
Fig. 1 is the connection diagram of the present invention.
Embodiment
A kind of comprehensive extracting and caving face returns device for coal, and it is trapezium structure to return device for coal 2, and the rear portion scraper plate of its upper surface is defeated
The connecting side of machine 1 is sent to be less than opposite side（Old man side）, the top of device for coal 2 is formed an inclined-plane, production period Sub-Level Caving process
In, it is defeated with regard to rear portion scraper plate can be directly introduced to by rebound 7 without being stacked into the height of rear portion drag conveyor inboard chute
Send in machine chute, ramp, which tilts, is more beneficial for coal landing, returns device for coal 2 and is connected to rear portion scraper plate conveying by connection ring 5
The side of machine 1, what connection ring 5 included being welded as a whole returns device for coal handing-over ear 4 and drag conveyor handing-over ear 3, and rebound 7 is fixed
On the top of connection ring 5, rebound 7 is less than go back to the upper surface of device for coal.
Returning inside device for coal has a supporting steel 6, serves as reinforcement rigidity, prevents from returning the damage of device for coal in production process
It is bad.
Return device for coal handing-over ear 4 and be provided with circular hole with drag conveyor handing-over ear 3, two handing-over ears are completed using round pin axle
Connection, connection of the device for coal by joining ear is returned during shifting is slipped can followed by rear portion drag conveyor movement.
The making of device：
1st, from the steel plate that thickness is 20mm, the long 1200mm of device for coal is returned, with rear portion drag conveyor connecting side height
260mm, old man side height 300mm, base width 400mm, ramp width 402mm.
2nd, the circular hole that device for coal handing-over ear is provided with diameter 22mm with drag conveyor handing-over ear, round pin shaft diameter are returned
20mm。
Above-described is only the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, these should also be considered as the present invention's
Protection domain.
